近场共振无线功率传输（R-WPT）具有效率高、传输范围广、射频辐射少等优点，在消费电子和生物植入等领域得到了广泛的应用。对于大多数应用，需要良好调节的输出电压来对抗耦合和负载变化，因此在R-WPT系统中应采用调节方案。为了实现最佳接收器（RX）或总体效率以及降低的成本开销，近年来已经提出了若干调节方案，其中调节可以在RX侧或发射器（TX）侧或两者处实现。本文对这些调节方案进行了综述和综合讨论。因此，本文的主要贡献是提供了一个指导原则，在R-WPT系统的调节方案的设计。此外，潜在的新拓扑结构的监管在这里进行了研究。
Owing to its relatively high efficiency, extended transmission range, and less exposure to radio frequency radiation, near-field resonant wireless power transfer (R-WPT) has been widely used in consumer electronics and bio-implants. For most applications, a well-regulated output voltage is required against the coupling and loading variations, and thus a regulation scheme should be employed in an R-WPT system. To achieve an optimal receiver (RX) or overall efficiency, together with a reduced cost overhead, several regulation schemes have been proposed in recent years, where the regulation can be implemented at either the RX or transmitter (TX) side, or both. These regulation schemes have been reviewed and comprehensively discussed in this paper. Hence, the main contribution of this paper is to provide a guideline for designing the regulation scheme in R-WPT systems. Moreover, potential new topologies of regulation are investigated here.
